For the record, the biggest entertainment would have been if you had seen the conversation I had with my son, the philosopher.
In the end, we concluded that a person can knowingly and willingly reject God, but at the same time (in the same instant) he cannot knowingly and willingly reject God.
Confusing?
It all depends on which definition we use for the word “knowingly”. If we use the word in the “propositional” sense, “he knows that…” , then yes, a person can “knowingly” reject God because he may know intellectually that what he is doing is wrong. When we use “that” after the word “know” we are using the word in the propositional sense.
However, if we use the word “knowingly” in the way that Jesus used the word “know” from the cross, no one ever knowingly rejects God because the word “know” means “affective knowing”, which means that the knowing includes emotional valuing. People do not reject what they value, and value of creation is truth. People do indeed sometimes value something false, but to the degree that they value something false, they do not affectively know what they are doing.
Make sense?
